[Live-devel] Help me please, "testRTSPClient"

[Felipe Lemos]

Ok Ross, thank you for explanations.

Last question!
Using the class QuickTimeFileSink, how to access the buffer and the number
of bytes captured RTSP.
DummySink this information are fReceiveBuffer and frameSize. I need access
to this data!

Thanks
